Referring to the memory card, how many GBs do I need for my Nikon D3000?

I'm a beginner, and I hear that it should be anything above Class 6 correct me if I'm wrong. I remember something about the photos "bursting"? Can someone please explain.

Added (1). Okay so note to self… DON'T do "burst" shooting… Thanks for the info I just wanted to be clear on what that was. And of course quality is better than quantity. Also how many pictures can a 2gb card hold? A 4gb?

Atleast 2 gigs

It is clear you are a beginner since you think burst shooting is a good idea.

Actually class 6 will help you discipline your shooting. So will buying four 2 gb cards like these

Burst shooting with any camera is a very bad habit.

If you take your time to compose each shot, the chances are you will shoot much better shots than if you just hold down the shutter release and hope for the best.

I'm a sports photographer and the most "burst shooting" I do is to shoot off three or four shots in five seconds.

Believe me, later going through all those shots burst shooting produce can be a huge pain in the gluteus maximus.

When you first start using your camera, spend at least a few minutes deciding how you want to compose the shot and how the lighting looks, making changes if necessary before you take the shot.

In photography, more is NOT better. Quality is. And quality takes some thinking and planning your shots.

I prefer using 4GB cards. I shoot in RAW and can fit about 300 shots on a card. The speed of the card doesn't matter unless you are shooting video or burst shots. I don't do video, but for the burst shots I prefer a 45+mb/second card.

There's nothing wrong with burst shooting, if you know why you are doing it. If you are hoping one of the shots will turn out, then don't do it… Practice honing your photography skills. But if you are shooting wildlife/animals/people in motion, it is a necessary. It is almost impossible to capture all 4 feet of an animal in the air when running full speed without it. One of the things I do for a lot of clients is an animated photo, from a dog chasing a ball, a dancer with her veil, a warrioress swinging a sword, to a bikini clad girl shooting a machine gun in addition to their other photos.
